Multi-ply wrap label
View Patent ↗A multi-ply, expanded content wrap label includes a base ply and an upper ply thereon with adhesive applied to the underside of a trailing end of the base ply to form a splice between the base ply and the upper side of the upper ply when the label is applied to a container.
1. A method of forming, in a single pass, a multi-ply label for application to a container having a known circumference, said label having an upper ply and a base ply with respective overlapping leading and trailing ends defining an end splice on application to said container, said method comprising the steps of:
feeding a first composite web comprising a liner and a releasably adhered upper ply to a press;
splitting said liner from said film;
printing one side of said film;
recombining said liner and said film;
turning said web 180 degrees;
printing another side of said film;
feeding a second composite web comprising a base liner and releasably adhered base ply;
splitting said base liner and said base ply;
printing one side of said base ply;
recombining said base liner and base ply;
turning said second composite web 180 degrees;
printing on another surface of said base ply;
introducing said second web to a die cutting station and cutting said base ply on said base liner, thereby forming a series of separate base label plies on said liner each of said base label plies having a trailing end portion with an under surface;
stripping away any portions of said base ply that are outside said series of base label plies;
splitting said liner and upper ply of said composite web;
removing said liner;
joining said upper ply to said second composite web;
cutting said upper ply to form a series of separate upper label plies on and in operative register with respective ones of said series of separate base label plies each of said upper label plies having a leading end portion with an upper surface, wherein an adhesive is disposed on said under surface of said base ply trailing end such that said adhesive is in a position to engage and adhere to said upper surface of the said leading end portion of said upper ply upon application of such label to a target surface;
stripping portions of said upper ply that are outside said upper label plies; and
rolling said base liner, carrying said base plies and upper label plies thereon, into a multi-ply label supply.
2. The method of claim 1 , wherein the step of cutting said upper ply includes cutting through portions of said base label plies.
3. The method of claim 2 , wherein said stripping of said upper ply includes stripping portions of said separate base label plies that are cut away when said separate upper label plies are formed.
4. A method of forming, in a single pass, a multi-ply label for application to a container having a known circumference, said label having an upper ply and a base ply with respective overlapping leading and trailing ends defining an end splice on application to said container, said method comprising the steps of:
providing an upper web including said upper ply and a liner, said upper ply defining an adhesive surface and a top surface;
providing a lower web including said base ply and a release support liner, said base ply defining an adhesive surface and a top surface;
splitting said upper ply and said liner;
printing on said adhesive surface of said upper ply;
recombining said upper ply and said liner;
flipping said upper web;
printing on said top surface of said upper ply;
feeding said upper web into a die cut section;
splitting said base ply and said release support liner;
printing on said adhesive surface of said base ply;
recombining said release support liner and said base ply;
flipping said lower web;
printing on said top surface of said base ply;
feeding said lower web into said die cut station;
cutting through said base ply of said lower web without cutting through said release support liner;
to thereby form a series of separate base label plies on said release support liner, each of said base label plies having a trailing end portion with an under surface;
splitting said upper ply of said upper web from said support liner;
joining said upper ply to said base ply of said lower web: and;
cutting through said upper ply and any portion of said base label plies in the path of this cut without cutting through said release support liner to form a series of separate upper label plies on and in operative register with respective ones of said series of separate base label plies, each of said upper label plies having a leading end portion with an upper surfaces, wherein an adhesive is disposed on said under surfaces of said base ply trailing end such that said adhesive is in a position to engage and adhere to said upper surfaces of said leading end portion of said upper ply upon application of such label to a target surfaces.
5. The method of claim 4 , wherein said upper ply and said liner are split and recombined a plurality of times, with said adhesive side of said upper ply being printed a plurality of times.
6. The method of claim 4 , wherein said top surface of said upper ply is printed using a plurality of print stations.
7. The method of claim 4 , wherein said base ply and said release support liner are split and recombined a plurality of times, with said adhesive side of said lower ply being printed a plurality of times.
8. The method of claim 4 , wherein said top surface of said base ply is printed using a plurality of print stations.
9. The method of claim 4 , wherein said flipping steps are accomplished by utilizing a turnbar apparatus.
10. A method of forming, in a single pass, a multi-ply label for application to a container having a known circumference, said method comprising the steps of:
providing an upper web including an upper ply and a liner, said upper ply defining an adhesive surface and a top surface;
providing a lower web including a base ply and a release support liner, said base ply defining an adhesive surface and a top surface;
printing on each surface of said upper ply;
printing on each surface of said lower ply;
feeding said lower web into a die cut section;
cutting said base ply on said release support liner, forming a series of separate base label plies on said release support liner each of said base label plies having a trailing end portion with an under surface;
joining said upper ply to said lower web; and
cutting said upper ply to form a series of separate upper label plies in operative register with respective ones of said series of separate base label plies, each of said upper label plies having a leading end portion with an upper surface, wherein an adhesive is disposed on said under surface of said base ply trailing end such that said adhesive is in a position to engage and adhere to said upper surface of said leading end portion of said upper ply upon application of such label to a target surface.
11. The method of claim 10 , further comprising the steps of splitting said upper ply and said liner prior to printing on said upper ply and recombining said upper ply and said liner after printing on said upper ply.
12. The method of claim 10 , further comprising a step of flipping said upper web prior to printing on said top surface of said upper ply.
13. The method of claim 10 , further comprising a step of removing said liner prior to joining said upper ply to said lower web.
14. The method of claim 10 , further comprising a step of stripping away portions of said base ply outside said series of base label plies.
15. The method of claim 10 , wherein the step of cutting said upper ply includes cutting through portions of said base label plies.
16. The method of claim 15 , wherein said stripping of said upper ply includes stripping portions of said separate base label plies cut away when said separate upper label plies are formed.
